IMPROVED MACHINE FOR MAKING SEWING-MACHINE NEEDLES.

the stamping, eyeing, and pointing being performed, the said parallelscrews will introduce the blank to two other parallel rotatingcarrying-screws, which aid in carrying the said blank (which is in likemanner rotated by endless belts) up against a cutter-wheel, which entsthe blank between the eyes, separating the needles, at the same timeremoving the burr from the needle-heads, and, finally, the said screwsdischarge the finished needles at the end of the machine.

Thus I produce an automatic machine for making two needlesby oneoperation and at oneY and the same time.

Having described the nature of my invention, I will now describe itsconstruction and operation;

In the said drawings, A indicates the driving-shaft, carrying abevel-gear, B, worms C C, spur-gear I), and pulley E, forming part ot'and operating the needle-machine. The bevelgear B engages with thebevel-gear B', rotating the shaft F, which carries on its inner end agear, G, which'engages with a gear, H, on the end of the feed-shaft I.Said feed-shaft carries a double-actin g cam, K, which operates the feedmechanism, consisting of a forked arm, L, (embracing the shaft I,) apin, M, projecting from said arm, a coiled spring, N, a lever, O, andbifurcated feed-plate I?, which receives the needle-blanks alternatelyfrom the hopper Q, and delivers the same to the progressive rollers R B,&o. (See Figs. 1 and 3.) These progressive carrying-rollers rotate ontheir shafts S S, which are station- To all whom fit may concern:

Be it knownl that I, F. W. MALLETT, of the necticut, lhave invented anew and useful Improvement in Machines for Making Sewinglowing is ageneral descriptionvthereof, reference being had to the accompanyingdrawings, making part of this specification, of whichl Figure 1vrepresents a front-side elevation; Fig. 2, a rear-side elevation; Fig.3, a plan or top view; Fig. 4, an elevation of feed end; Fig. 5, anelevation of opposite end; and Fig. 6, a transverse section of saidmachine, taken on line w of Fig. 1. Figs. 7, 8, and 9 are views ofone'of the progressive rollers, as removed from the machine, showing theoperative mechanism for taking up, carrying, and delivering theneedle-blanks to the next progressive roller, as well as to the parallelcarrying-screws. l

This invention relates to an improvement in the class of self-actingmachines for making needles; and consists of a peculiar combination ofmechanism by which two sewing-needles are made by one operation, and atone and the same time, in the following manner: In the first place, thewires or blanks, being cut to the desired length for two needles, arethrown into a hopper, which has, in connection withthe same, a'feedingdevice, which conveys one'blank at a time to the first set-of a seriesof progressive carrying-rollers, which take up the blanks in turn andcarry them from oneY to the other; and while being so ary, and aresustained in a bearing, T, On the carried by the rollers, the saidneedle-blanks table U of the machine. Said rollers carry are stamped,the eyes punched, and the eyes gears VV, which engage withcarrying-gears tested by a feeler, which will detect the blank NV W, andwith gears X X on the feed-sh aft not properly eyed, and will stop thefeed mech- I, by means of which motion is imparted to anism'for itsremoval; second, the blanks bethe series of progressivecarrying-rollers, as ing properly stamped, eyed, and burnished, shown inFigs. 1 and 3.

for stamping the blank preparatory to punching the eyes in the same.This stamp is operated by a cam, c, on the end of the shaft d, and aspring, e, attached to the case j, said shaft d being rotated by theshaft F and intermediate gears ell di.

g is the punch, and h a perforated block, for punching the eyes in theblank needles, and it consists of a sliding bar, z', with punches jj,said sliding bar being operated by an eccentric, j', attached to theshaft d, as shown in Figs. 1 and 6.
